Rpplc'aton 'led September 2, -lg Serial fo. Ar53,969.`

This innen-tion rela/tes, generally, to proyeinents in .heat-ers; and, the invention has reference, more particularly, toa novel and simply .ooiristructed apparatus adapt-.ed for use a heater 'employed for leactjiological 'and other purposes, 'and especially for the production and the handlii'ig of antitoxins 'and cultures. I

The present invention has for its principal 'ob'i'fe'ct the production of a heater 'ci the generali construction hereinafter `more fully set forth, .provided with means Within the apparatus for generating heat Within the apparatus at ipoint near the door thereof7V which is usually 'the coolest portion 'of the chamber., and, furthermore, providing in connection with the chamber of the apparatus, means which will produce fa vcii`"'cu-l`ation of the heat `ait a point at the rear and lower portion of the chamber, Vthen in a direction forwardly at fthe bottoni of the chamber, then upwardly at 'the front of the cli-amber, along the coldest part thereof, then ahime the top of the chamber, rearwardly toward r the back off the same, and lin-ally in a direc tion downwardly at the rear of Vthe chainb'er, to the bottom off fthe salire. i

The invention has for its 'further object to provide inconnection with a heater of the character hereinafter 'set forth an felectrically operated mechanism -pr'oyide'd Ewith automatic means, lwhich can be set to any desired deg-ree of healithat may be desired, so that a const-.ant temperature oli' heat is readily and automatically maintained Within ,the chamber of the apparatus. (ther objects of this invention not 'at this time more particularly enumerated will be more fully understood from the following detailed description of the said invention.

Similar characters fof reference are einployed vin the said above described views, toin-'dc ate corresponding parts;

Reife-r o; new `to 'thejsaifd drawings, the reference-:characterl indicates, in a generati maniier, a lifeatingapparlatus made according; to and oinlbodjjfing the principles of the present invention, the saine comprising fai suitably sli-:sped :casing or lioix), usually 'ofthe 'configuration fshoWn. 'This casing or Abox consists, essentially, of fa suitably shaped lisse-plete comprisin'gl two members@ sind' 3,secnrecl by 'means of' rivets 2l, or any other suitable manner, to a 11e-enforcing or strengthening trame, shown :more particulfariy in e sure v11 of the drawings. 'This treme consists, essentially, of theffouter msrcinsl masters .6., provided 'with the l depending' flanges or ribs' '7, and a'transyeifse ly extendi c; niemeer 18, also 'provided `wrfit'h a` depending lrib `Si). JOne of 'saifd marginal nienibers '6 is iiofrnied with an upwardly proL jecting;` flange, as 1Q, the sali/d flanges or 7 of the niembers,

at die corners of the iframe, by means or' Suitably secured to -1 electricrveld-infg, 'or otherwise, are suitablythe rear wall is also provided at its lower marginal edge, with an-A inwardly curved portion- 16 and an upwardly extending flange 17, arranged to form a receiving space 18. .A space 19is also left between the outerfaces of the'previouslymentioned ribs or flanges 7 `and the inner lower faceportions of the side and end-plates 12. The upper wall of the casing or box consists of two plates' 2O and 21, the inner plate 21 being provided with spacing flanges 22, ar rangedl substantially as indicated in said Figures 2 and 3, the plateA 20 being secured to the marginal flanges 14 of the rear and side-wall plates 12, in any suitable manner, and preferably by means of the bent-over edge-portions 23. At the front of the casing or boxv is a vertically disposed frame like element 24, which may bere-enforced by anarrangement of ribs,as 25, the upper portion of said element 24 being made with an outwardly extendingl marginal flange 26 to which the plate 2O is kalso suitablysecured, preferably byl means of the bent-over edge-portion 27 of said plate 2t@ The lower marginal edge-portion of said frame-like element 24 terminates in front of the adjacent rib or flange 7 of the corresponding frame-member 6, a space 28being left between the outer face -of the said rib or flange 7 and the 'inner face of said lower portion yof the frame-like element`24.` As shown, the said framedike element 24 is provided along the lower marginal portion of its vopening, .withl an-,inwardly extending member 29 bounded by a right' angled flange 30. f* l At one side, the said framedike element 24 is provided upon its outer face with pintle-receiving ears or hinge-members 31, andk upon its voppositely located side with a suitably constructed latch or catch-receiving member,- as 32. f

The openvportion of said frame-like element 24 is adapted vto be lclosed by means of'a door, which 'is preferably constructed as shown'in Figures 1, 3 and 9 of the drawings, and which consists, essentially,foffa front frame-member k33, formed with curved marginal edge-portions 34, bounded by the inwardlyextending angularportions 35 and 36. f

Suitably secured against said Portion 36, are marginaly angular portions 38 of an inner or rear frame-member `The said front or outery frame-member 33 is also formed withv inwardly extending spacing frame is .also provided with a lock-catch 44, or other suitable closing or lockingy means, adapted to be brought into retaining engagement with the previously mentioned catch or latch-receiving'means 32, as will be understood. The frame-like element 33' is also provided with` perforated pintle-receiving ears or hinge-members 45, in alinement with they cars ory hinge-members 31, for reception of a pin or rod`46, for operatively attaching'y the door, thus provided, to the' front of the casing or box.

The hollow rear and side-walls, the hollow top-wall, and the hollow door-frame formed by the above described assembled members are respectively filled with suitable heat-insulating material 47, 48 and 49. Within the main chamber of the apparatus, the plates 13 of the sidewalls may also have suitably secured thereon, suitably constructed and suitably disposed tray-receiving cleats, as 50. Within the lower portion of said nrain chamber is a suitable plate 51 held in place by a right angled flange 52 extending into the previously mentioned receiving space 18, at the rear, and by a laterallyfextending supporting plate or bar 53, near the front of said chamber. Blockshaped elements 54 and 55 are arranged, respectively, against r,the inner face of the lower portion of the frame-member 24 and upon thev marginal member 6 of the lower frame of the apparat-us, the block 55 being formed with a yseries of suitably disposed Ventil-ating perforations 56 in registration with perforations 57 correspondingly placed in the plate 2. At its rear portion, the plate 51 is also provided with a series of perforations 58, and at its front edge'the said plate 51 has an upwardly extending Vdow-glasses'or plates 42 and 43.
